Vitamin D and sunshine
Vitamin D is essential for calcium absorption and many other biological processes. Lower levels of Vitamin D increase the rates of almost every disease like cancer, diabetes, osteoporosis, cognitiv...
Vitamin D supplementation
Getting vitamin D through supplementation shows zero benefits. A study over a period of 5 years found supplementing with Vitamin D had no impact on cancer, heart disease, or stroke.

Sunlight is good for you
A dermatologist discovered our skin uses sunlight to make nitric oxide, a molecule in the body that dilates blood vessels and lowers blood pressure.
He exposed volunteers to the equivalent of 30 minutes of summer sunlight without sunscreen. The result? The nitric oxide levels in the volunteers went up, and their blood pressure lowered. Because of the connection of high blood pressure to heart disease and strokes, this discovery can prevent millions of deaths globally.
